Digital bathymetry for site at Killary Harbour, Ireland

OceanSpar helps prospective and existing clients evaluate open ocean sites for grow-out suitability. We develop the information and analysis required to help them make informed decisions about the technical and economic viability of target aquaculture sites.

Objectives

Project objectives typically include an assessment of site characteristics, including fish pen engineering requirements, ability to support stocking, feeding and harvesting operations, and the site’s general appropriateness for fish grow-out. We also assess the land-based characteristics of the site, including its ability to support farm operations and integrate with other marine aquaculture activities such as hatchery operations, processing and distribution.

Approach

Key activities include collection of publicly available oceanographic data and directly observed data from current meters and other sensors. During a site visit, we typically conduct a land-based tour of the area to assess infrastructure, take seabed core samples (if allowed), and assess the benthic strata for an anchoring solution. Analysis activities include fish pen drag modeling and load calculations to determine optimal anchor tensions and locations. In some cases, OceanSpar will also help clients develop an economic pro-forma for the site, including a preliminary cost budget and scenarios to support fund-raising activities.

Deliverables

Data, computer models, key findings and conclusions are assembled and packaged for review with the client. In addition to helping clients make an informed decision on the viability of the site, our information can be used to support Environmental Assessment reports for permit applications and biota physiological studies to determine appropriate fish species, grow-out rates, biomass loading, effluent dispersion rates and projected long-term benthic effects.
